Khulnasoft Tunnel client

Contains the command-line client for Khulnasoft Tunnel, a tunneling daemon that proxies traffic from the Khulnasoft network to your origins. This daemon sits between Khulnasoft network and your origin (e.g. a webserver). Khulnasoft attracts client requests and sends them to you via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible. Extensive documentation can be found in the Khulnasoft Tunnel section of the Khulnasoft Docs. All usages related with proxying to your origins are available under tunnellink tunnel help.

You can also use tunnellink to access Tunnel origins (that are protected with tunnellink tunnel) for TCP traffic at Layer 4 (i.e., not HTTP/websocket), which is relevant for use cases such as SSH, RDP, etc. Such usages are available under tunnellink access help.

You can instead use WARP client to access private origins behind Tunnels for Layer 4 traffic without requiring tunnellink access commands on the client side.

Before you get started

Before you use Khulnasoft Tunnel, you'll need to complete a few steps in the Khulnasoft dashboard: you need to add a website to your Khulnasoft account. Note that today it is possible to use Tunnel without a website (e.g. for private routing), but for legacy reasons this requirement is still necessary:

1. Add a website to Khulnasoft
2. Change your domain nameservers to Khulnasoft

Creating Tunnels and routing traffic

Once installed, you can authenticate tunnellink into your Khulnasoft account and begin creating Tunnels to serve traffic to your origins.

• Create a Tunnel with these instructions
• Route traffic to that Tunnel:
  • Via public DNS records in Khulnasoft
  • Or via a public hostname guided by a Khulnasoft Load Balancer
  • Or from WARP client private traffic

TryKhulnasoft
